Sensor arrangement

1. A sensor arrangement for detecting fogging on a glass pane, comprising:

a support plate;

a sensor element in thermal communication with said glass pane, wherein said sensor element is arranged on said support plate and is sensitive to moisture; and

a contact element that thermally couples said sensor element with said glass pane, wherein said contact element is fastened on said support plate so as to enclose said support plate to a large extent in a contact area where said contact element contacts said glass pane, wherein said contact element is elastic and can be slipped on said support plate under mechanical tension.

2. The sensor arrangement in accordance with claim 1 , wherein said contact element defines a cutout that is positioned in an area of said sensor element and which has dimensions that approximately correspond to dimensions of said sensor element.

3. The sensor arrangement in accordance with claim 1 , wherein said contact element comprises a material with high heat-conducting capabilities.

4. The sensor arrangement in accordance with claim 1 , wherein said contact element comprises a metal spring.

5. The sensor arrangement in accordance with claim 4 , further comprising an electrically insulating layer, which is capable of conducting heat, that is arranged in said contact area between said metal spring and said support plate.

6. The sensor arrangement in accordance with claim 4 , further comprising an electrically insulating layer, which is capable of conducting heat, that is arranged in said contact area between said metal spring and said glass pane.

7. The sensor arrangement in accordance with claim 5 , wherein said electrically insulating layer comprises a self-adhesive polyimide layer.

8. The sensor arrangement in accordance with claim 6 , wherein said electrically insulating layer comprises a self-adhesive polyimide layer.

9. The sensor arrangement in accordance with claim 4 , wherein said metal spring is made from a material selected from the group consisting of copper, aluminum and spring steel.

10. The sensor arrangement in accordance with claim 1 , wherein said contact element comprises a plastic sleeve which can be slipped on said support plate.

11. The sensor arrangement in accordance with claim 10 , wherein said plastic sleeve comprises a T-shaped cross section that defines a cross support and a longitudinal section attached thereto, wherein said cross support is provided for contact with said glass pane, and said support plate with said sensor element is arranged in said longitudinal section of said plastic sleeve.

12. The sensor arrangement in accordance with claim 10 , wherein said plastic sleeve comprises a silicon material filled with a heat-conducting ceramic material.

13. The sensor arrangement in accordance with claim 10 , wherein connecting lines of said sensor element are arranged in a direction toward said glass pane.

14. The sensor arrangement in accordance with claim 13 , wherein said connecting lines of said sensor element are designed with large surfaces.

15. The sensor arrangement in accordance with claim 1 , further comprising a temperature-sensitive element arranged on said support plate.

16. The sensor arrangement in accordance with claim 1 , wherein at least in an area of said contact element said support plate comprises bores which are provided with a layer capable of conducting heat.

17. The sensor arrangement in accordance with claim 1 , wherein said sensor element is mounted above a cutout of said support plate, wherein a moisture-sensitive side of said sensor element is oriented in a direction toward said cutout.

18. A sensor arrangement for detecting fogging on a glass pane, comprising:

a support plate;

a sensor element in thermal communication with said glass pane, wherein said sensor element is arranged on said support plate and is sensitive to moisture; and

a contact element that thermally couples said sensor element with said glass pane, wherein said contact element is fastened on said support plate so as to enclose said support plate to a large extent in a contact area where said contact element contacts said glass pane, wherein said contact element comprises a metal spring.

19. A sensor arrangement for detecting fogging on a glass pane, comprising:

a support plate;

a sensor element in thermal communication with said glass pane, wherein said sensor element is arranged on said support plate and is sensitive to moisture; and

a contact element that thermally couples said sensor element with said glass pane, wherein said contact element is fastened on said support plate so as to enclose said support plate to a large extent in a contact area where said contact element contacts said glass pane, wherein said contact element comprises a plastic sleeve which can be slipped on said support plate.
